People love leftovers, however its taste is not as good as freshly prepared. The good thing about this is that you can warm it in the microwave and it is ready for consumption.

You need to learn which foods are good to be heated and which are not for some of the leftovers can turn into toxic meals which provide less nutrients compared to the freshly prepared.

These are the foods you should never reheat again:

Rice

The main issue about eating the leftovers is the way how they are stored. There might be spores of harmful bacteria which survive through the initial cooking process.

Three of the Most Dangerous Leftovers

If you don’t keep the leftover rice at the right temperature, then the spores will spread and multiply, causing digestion issues like vomiting or diarrhea if eaten.

If the rice is reheated the spores will not be destroyed as they can survive even at boiling hot temperatures.

The best thing is to consume the rice immediately after is preparation. Do not let it stay at a room temperature longer than 1 hour. The longer it is left out the more dangerous it is.

Vegetable oil

If you reheat meals with vegetable oil for leftover you may be at risk of heart stroke and cancer.

According to a latest research, repeatedly heating up polyunsaturated oils which have linoleic acid like canola, corn, sunflower, and soybean can release toxic compounds which cause many different health disorders.

The word is about a fatty acid named 4-hydroxy-trans-2-nonrnal (HNE) which is associated with many health conditions like including cancer, liver ailments, Huntington’s disease, Alzheimer’s, Parkinson’s disease, stroke, and cardiovascular disease.

If the vegetable oil is too much or constantly reheated it can release HNE, according to the American Dietetic Association. Their spokeswoman, Jeannie Moloo, said that if one person is concerned about the health aspects of HNE, then do not heat any oil to the point of smoking, just use the oil in time.

Vegetables

Many people say that if leafy green vegetables are reheated they become poisonous, but the issue here is the way of storing them. The leftover veggies should be put in an area where the temperature is below 4 degrees Celsius.

In case you want to store them for longer than 12 hours then freeze them. Many vegetables like lettuce, spinach, beets, and celery contain great amounts of nitrate which itself is not harmful.

But the vegetables which are left at room temperature can cause nitrates turn into nitrites, which are harmful to infants and young children causing blood disorder named methaemoglobinaemia with symptoms like seizures, shortness of breath, fatigue, and headaches. - Online Sources
